My invention relates to portable woodworking machines, and its objects are to provide a wood-working machineV of simple and strong construction whichA may beeasily wheeled from place to'v place; with which the lumber used for building'v purposes may be quickly cut 'Ona bandI saw, circularsaw or a planer 'to an accurate ht.

These objects, and otherL advantage-ous ends which will be 'described hereinafter, I `attain in the following manner, reference being had to the"accompanying, drawings in which Figure '1`is 'a side elevation'of a portable woodworking machine constructed in accordance with my invention,

Referring to the drawings, 1 indicates a frame which'V is made up of 'angle bars 2 Vand `tie plates -8 connected to form a boxsl'ia'pe base having a platform 4 en which an internal combustion engine 51er- 'an electric motor is mounted.' The frame is wheeled onl a pair of wheels o having stud shafts? rotatable in bearings 8 secured to the angle bars 2 of the frame. The frame is supported in vwoodworkingposition by a pair ofpiv'ot'ed legs-9 held in `fixed position by braces 10 pivoted to the legs and detachably connected with the frame at 11. A handle 12 is pivoted to `ythe frame so that it may be swung out ef the way, as lshown in vdo`t-and-dash lines in Figure` 1, when the frame is -in wood-working position, and is held in wheeling position 'by a pair 'of braces 18 pivoted to. the handle and detachably connected with 'the' frame 14. Apair of the angle bars 2-1of the frame is preferably secureddiagonally to provide a `support .for bearings 15 in which adrive line 7 'mounted on'the frame at 31. Tensionmay shaft 1G`is rotatably mounted. This drive shaft carries a fixed pulley 17 and a loosely -mountedpulley 18 which may be operatively connected witha belt 19, connected with envgine '-5, by belt shift-ing mechanism. yThe belt `shifting mechanism consists of a pair of opposed belt pushers 2O fixed to a slidable rod 2l connected with a lever 22 pivoted von the frame at 23.

A lar-ge belt bulley 24 lined with the loosely mounted pulley 18 rotates with it 'about drive shaft 1G.v rlhis pulley transmits its movement 4through a Vbelt 25 to a small pulley 26 on a jointer shaft 2'? rotatable in lsuitable bearings 28 fixed to the frame. rlhe jointer shaft is connected with the large pulley 2li by tightening belt 25. Belt 25 is placed under tension and released by an idler pulley 29rotatable in hangers 30 swingably be placed on the belt by swingingthe idler pulley against the belt by a handle 32 notched at 38 for engaging the edge 34 cfa* slotted member on the frame to hold the pulley in position against the belt. ,y The tension on the belt may be released by swinging t-he pulley away fromfthe belt.

' A jointerhead 35 is secured to the shaft between bearings 2S, and a circular saw 35 is removably secured to lthe end of the shaft `outside the left bearing 28. A jointer table consists of a rear part 38, mounted 'on the frame for vertical adjustment'by linksl 39 secured by bolts 4:0', and a front'part'fll mounted on the frame for. adjustment by links4l-2 and an adjusting screw 43. The

ladjusting screw is-swivcled to the front table part 41 'at 424i and to the frame at 45.` By .turning screw 43, the front tabler part 4:1

vvmay be elevated'by links d2. A. circular saw '9 ytable 46 has one end pivoted tothe rear jointer table part 38 at l? and the other end normally resting on the Vfront jointer table part 111. i The circular saw table is adjusted vertically by ka screw 48 threaded in the part 41, and has slit eil/through. which ther saw 3G extends. A. dovetail groove 50 in the top of table 4156 receives a tenen 51 of a lumber guide 52 so thatfit may be adjusted rela- 'tively to the circularl saw 3G. The guide is held in adjusted position by a screw 53 threaded in tenenv 51, by screwing its end into binding engagement with the bottomof the dovet'ail groove.

Drive shaft 16 carries a band saw pulley L as 54 which drives a `band saw 55 passing over it and a second pulley 56 mounted above the frame. Pulley 56 isrotatably mounted on a bearing in the form of a stud shaft 57 integral with a sleeve 56 adjustable on an upright tubular guide 59 fixed to an extension 60 on the frame. Extension 60 is in the form of a channel secured to and forming a part of the frame made of the angle bars 2 and plates 3. Sleeve 58 has a pin 6 1 fixed thereto and passing through a slot 62 in guide59. 'Ihe sleeve is adjusted vertically by a screw 63, threaded in extension 60, and is yieldably ,held in adjusted position by a spring 64 mounted between screw 63 and `pin 61. Suitable disks 65 are attached to each end of the spring to provide efficient bearing ends on the spring.

A band saw table 66 has an opening 67 through which band saw 55 passes. The table is tiltably mounted on a frame member 67 and held in position by a single bolt 68 passing through member 67 and a pair of lugs 69 disposed at opposite sides of the member 67. Table 66 is normally level with the circular saw table 46 and adjacent thereto so that either table serves as an extension for the other.

Y rllhe machine above set forth may be easily wheeled from `place to place by simply swinging the legs 9 out of the way as shown in dot-and-dash line position at 70 in Fig ure 1 and balancing the machine withgthe handle 12. The machine is set in wood working position by swinging the legs 9 to `the full line position and the handle 12 to the dot-and-dash line position shown in Figure 1. The lumber may then be cut on the band saw 55 or circular saw 36. Then it is desired to plane the lumber, the circular saw table 46 is removed from the jointer table by removing the pivot bolts 47. The jointer `table will then be as shown in Figure 4 and the lumber may be readily planed by passing it over the jointer head u To operate the jointer or circular saw, belt 19 is shifted onto pulley 18 by operating the lever 22 and its associated parts, to rotate the pulley 24. To connect this pulley with the pulley 26 on the jointer shaft, the idler pulley 29 is swung against the belt 25 by handle 32 until one of the notches 33 fits over edge 34 on the slotted member on the frame. The tension placed on the belt will causeit to rotate with pulley 24 and thus transmit movement to jointer shaft 27. The circular saw and ointer head are stopped by swinging idler pulley 29 from belt 25 to release the tension on-the belt.

' To operate the band saw, belt 19 is shifted onto the pulley 17 by -operating lever 22 and the parts connected therewith. Pulley 19, being fixed on drive shaft 16, will rotate the same and the band saw pulley 54 around which the band saw passes. Any desired tension may be placed on the band saw by adjusting the screw 63 against spring 64.

The band saw table may be adjusted to any tilted position and held in that position by loosening bolt68, tilting the table and circular saw table 46 may be adjusted by turning the screw 38 and the( depth of cut to be planed byjointer head 35 may be regulated by adjusting the front part 41 of the planer table by the screw 43 which causes the part 41 to be elevated or lowered by the swinging oflinks 42. a

It will be seen that with a portable woodworking machineV as above set forth, lum- 70 tightening the bolt again. The height ,of-

ber used in building construction may be quickly cut to fit, and the machine may be easily transported from place to place. j

Vhile I have described my invention as taking a particular form, it willvbe under-` stood that `the various parts may be changed without departing from the spirit thereof, and hence I do not limit myself to theprecise construction set forth, but consider that I am at libertyto make such changes Vand alterations as fairly come within the scope of the appended claims. y

Having thus described my invention, what VI cla-im as new and desire to secure by Leptters Patent is :M
